Basic Python, Chapter 8

P8.17 Write a program that reads the data from https://www.cia.gov/library/publications/ the-world-factbook/rankorder/rawdata_2004.txt into a dictionary whose keys are country names and whose values are per capita incomes. Then the program should prompt the user to enter country names and print the corresponding values. Stop when the user enters quit.

P8.18 The program of Exercise P8.17 is not very user-friendly because it requires the user to know the exact spelling of the country name. As an enhancement, whenever a user enters a single letter, print all countries that start with that letter. Use a dictionary whose keys are letters and whose values are sets of country names
